aaronI'll share a troubling fact with you if you share one with me
If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack.
If that counter attack is headed to North Korea, any land based missiles will head over the arctic circle, over Russian airspace where similar shoot/no shoot decisions will have to be made.
There’s an anecdote about a U2 naming a song “One Minute Warning” if I recall correctly: many years ago, when a UK prime minister learned the US got 6 minutes, they asked how long the UK would have. The response: “I suppose we’d have about a minute.”
